Pre-Mesozoic Alpine basements—Their place in the European Paleozoic framework

Raumer, Jürgen F. von ; Bussy, François ; Schaltegger, Urs ; Schulz, Bernhard ; Stampfli, Gérard M.

In: Bulletin of the Geological Society of America, 2013, vol. 125, no. 1-2, p. 89-108

Prior to their Alpine overprinting, most of the pre-Mesozoic basement areas in Alpine orogenic structures shared a complex evolution, starting with Neoproterozoic sediments that are thought to have received detrital input from both West and East Gondwanan cratonic sources. A subsequent Neoproterozoic–Cambrian active margin setting at the Gondwana margin was followed by a Cambrian–Ordovician...

The Variscan evolution in the External massifs of the Alps and place in their Variscan framework

Raumer, Jürgen F. von ; Bussy, François ; Stampfli, Gérard M.

In: Comptes Rendus Geosciences, 2009, vol. 341, no. 2-3, p. 239-252

In the general discussion on the Variscan evolution of central Europe the pre-Mesozoic basement of the Alps is, in many cases, only included with hesitation. Relatively well-preserved from Alpine metamorphism, the Alpine External massifs can serve as an excellent example of evolution of the Variscan basement, including the earliest Gondwana-derived microcontinents with Cadomian relics.
